Discussion

 This is the common "seagull" inland and along the coast. In recent decades it has become abundant, probably due to the amount of food available at garbage dumps, and has extended its range southward along the Atlantic Coast, often to the detriment of colonial birds such as terns and Laughing Gulls. Although a scavenger, it also eats large numbers of aquatic and marine animals and feeds on berries. It often drops clams and other shellfish on exposed rocks or parking lots in order to break the shells and get at the soft interior.
